摘要

Chondroblastoma is a benign but rare cartilage-forming neoplasm that accounts for nearly 1% of all primary bone tumors, predominantly in long bones of extremities. Clinical presentation of chondroblastoma may be too unspecific to diagnose precisely and relate to other similar medical condition/ disorder. For making appropriate diagnosis of chondroblastoma, it is necessary to be differentiated by immunohistochemical analysis and H&E stain. A case of a mid-seventies man came to our institute with chief complaint of a 2-cm painless mass at his left pre-auricular area for more than one year which was growing a little bit larger than it was recently. In clinic, it was most likely to be pleomorphic adenoma of parotid gland based on clinical manifestation. This mass was removed smoothly without complication and its pathological report was chondroblastoma. We presented a rare case of chondroblastoma of the mandibular condyle which was mimicking a mixed tumor in clinic.

軟骨母細胞瘤爲一良性但是罕見的軟骨性腫瘤，好發於四肢長骨，頭頸部軟骨母細胞瘤發生極爲罕見。臨床上要直接診斷出軟骨母細胞瘤不容易，因爲與其他腫瘤的臨床特徵很雷同不易分辨，需要免疫組織化學染色來做鑑別診斷。一位70歲男性，主訴於一年前左側耳前臉部有一無痛之腫塊，因爲近期發現有略爲腫大而至本院求診。依據臨床表現懷疑是耳下腺唾液腺良性多性腺瘤，故安排腫瘤切除手術，術後無併發症，病理報告卻是爲下顎骨髁突之軟骨母細胞瘤。由於罕見，故提出病例報告。
